Building workout plans: Excel, templates or software?

The most common start. You know your client, you write out a plan in a document or on paper, and you adjust it when needed. The quality is usually highest, because you genuinely think about every choice.

The problem is pure arithmetic. Count 30 to 60 minutes per block per client. At five clients that is half a day a month, perfectly doable. At twenty clients it is a full working week per month of unpaid work.

The logical next step: build one good plan and adjust it slightly per client. That speeds things up enormously and keeps everything in one place.

The trap is that adaptations quietly disappear. A client with knee complaints still gets the standard lunges on copying, because that line was already in the template. Excel checks nothing, it only remembers what you typed. At ten clients or more it also becomes hard to track which version of which template is where.

A second limitation: Excel does not know what equipment your client has. Someone training at home with two dumbbells gets exercises they cannot perform in a copied gym plan, unless you check that manually every time.

Software takes over the rules: which exercise suits this goal, which one drops out for this injury, what equipment is available, how much the load builds. What you enter is the client; what you get back is a complete block.

The gain is not only speed but consistency. A filter that excludes injuries never forgets, not even on a busy Friday evening. That is exactly where manual workflows fail.

The flip side: you give up part of the fine-tuning. Software picks along rules, not along your feeling about that one client. Good software solves that by letting you steer through the input — goal, level, equipment and frequency — and by stating honestly when a choice deviates from a guideline.

Up to roughly five clients, writing plans yourself is fine and probably the best choice, because the time saved does not yet outweigh the cost of a subscription.

Between five and fifteen clients the admin starts to pinch. Templates help, but the risk of mistakes rises as the variation between clients grows.

Above fifteen clients working by hand usually becomes unsustainable without losing quality. That is typically the point where software pays for itself: if one saved hour a week is already worth more than the monthly price, the case is quickly made.

• Can you record injuries per client, and are unsafe exercises then actually excluded?
• Does the system account for available equipment, or does it assume a full gym?
• Does the load build progressively across a block, or do you get separate sessions?
• Can you hand the result to your client as a clean PDF?
• Is it clear what the dosage rules are based on, or do you have to take the vendor's word for it?
